 Function
Three acceleration times and three deceleration times can be specified individually. A method of
selection or switching can be selected from among the following:
S-pattern 2 acceleration/deceleration
Select this pattern to obtain slow acceleration in a demagnetizing region with a small motor
acceleration torque. This pattern is suitable for high-speed spindle operation.
